The amp is insufficient to drive the speakers to the levels you are getting. It would run out of power and clip. If it is an older amp over 15 years some of the power supply caps might be out of spec and one channel can run out of power before the other. So first swap channels to see if the problem remains on the same amp channel.Alternately try another more powerful amp.

The mid/tweeter driver can not produce the kind of problem you are describing on its own. That said, if it is the problem BG RD drivers might be available again for the DIY community as their Neo drivers have been made available recently but Parts Epress' stock is already out. An alternative is a line of Neo8 PDR drivers. Costly but very good.

The woofers are likely to have problems first since the speakers are old and they may need new surrounds (refoaming) not a costly project and can be done DIY. The problem you describe sounds more like a woofer problem. Another problem can be a crossover cap being out of spec. IIRC they used an electrolytic cap in the bass low pass filter.
